SPECIFICATION forming part of Letters Patent No. 733,865, datedFebruary' 28, 1905.

Application led November 11, 1903. Serial No. 180,742.

Be it known that I, A'Lois HLA, a subject of the Emperor ofAustria-Hungary, and a resident of Pilsen, Bohemia, Austria-Hungary,

have invented certain new and useful Improvements in Rotary Motors; andI do hereby declare the following to he a full, clear, and ein actdescription of the invention, suoli as will enable others skilled in theart to which it ap- IO pertains to make and use the saine.

My invention relates to a rotary steam or like motor.

In the accompanying drawings, Figure 1 is a vertical section of themotor, taken on the I5 lines I I and II II of Fig. 2. Fig. 2 is ahorizontal section taken' on the lines III III and IV IV of Fig. Fig. 3is a vertical crosssection on the lines V V and V1 VI of Fig. 2. Figs.f1 to 15 show details to he hereinafter 2O referred to.

The motor consists of the steain-cylinder a, provided with covers Z1 andsteam-regulat ing chambers c c', of the shaft 7, slide c, valve g, andgovernor Frein either side of the motor two passages 1 1 and 2 2 conductfreni the steai'n-ehanibers c c into the steam-cylinder a, Figs. 1 to 3,6, 7, for the live-steam supply and for exhaust, respectively. Each ofthe upper passages 1 1 branches into two,

channels leading from the body of the cylinder to the covers 7) 7) andentering the chamher of the cylinder' at 3 and 3' adjacent to the slidee. These passages remain open for permanent supply of steam, the latterbeing 3 5 regulated by slide-valves f1 and L1 in the stean1- chambers cc'. The lower passages 2 2 likei wise lhifurcate into two channels,which enter the cylinder-chamber at 5 and and are closed hy valves 6 and6 in the steam-chambers.

In the steam-cylinder c is a working' meinher d, Figs. 1 to 3, 8 to 12,keyed tothe shaft 7 and comprising a cylinder 8 and a flange or ringconsisting ol." two separate sectors 9 and El', of which the one islocated at one end of the cylinder and the other one at the opposite endin such manner that they stand at an angle of one hundred and eightydegrees rela tive to each other. rIhese two sectors 9 9 are connectedwith each other by screw-blades 10 and 10Q of which the one, 10, isright-hand- 50 ed and the other, 10', left-handed.

Figs. 8 to lOshow side elevations of the member Z with its flange inthree different positions. Fig. 11 shows an end elevation of the same.and Fig. 12 a section on the line VIII VIII of Fig. 8.

The slide e, Figs 1, 2, 13 to 15, has the forni of a long plate and iswith one of its narrow sides, 11, always hearing against the surface ofthe cylinder 8, Figs 1, 8 to 10. It is provided at the center with arecess 12, in which the flange of the cylinder 8 engages, so that theslide is moved positively to and fro. At either side of the recess 19are jaws 13 13', pressed against the iiange of the cylinder t3 Vbysprings 14 for the purpose of making' tight joints. The slide c ispressed against the cylinder 8 by theplate 15, which again is under theinfluence o1 the spring 16. The jaws are ehanifered at their inner inneredges, so that the surfaces 17 lie against the sectors and the inclinedfaces 17' against the screw-blades.

The valve y, Figs, 1 to 5, consists of a casing 18,` to which four pipesare holtedmviz., the pipe 19 with valve 20 for the steam-supply, thepipes 21 and 21' connecting the valve g/ with the steam-chambers c c,and finally the exhaust-pipe 22. Inside the casing 18 is a conicalvalve-body 23, having two chambers and mounted on a spindle. 'Ihevalve-body can be adjusted in three different positions wt, n, and o forthe various steaxnways. ln the position wt the steani-sinfiply iscutolf. In position a steam enters the pipe 21, and in position o steamenters the pipe 21.

The speed of lthe motor is controlled by the governor ri, driven fromthe shaft 7 by means of pulleys 211 and cord 25.

26 is a sliding sleeve to which is connected the double arm 27, which bymeans of rods work the slide-valves l1 il', which close and open thepassages 1 1 After openingl of the valve r/ into the position a steamenters the pipe 21 and chamber c, and from here through the passage 1and the two holes 3 at the side of the slide e into the steam-cylinder.The steam cannot escape through the passage 2, as the valve (5 is forceddown by the live steam above. The steam reaches the cylinder 8 andenters the chambers s and s, Fig. 8, which arel enlarged by thesteam-pressure, and thus set the cylinder 8 in rotation. Thesteam-supply passages are closed at the proper moment and the chambersfilled with steam arrive at the other side of the slide, where the steamcommences to rush out through the holes 5f and passage 2 into thesteam-chamber c. When this passage 2/ no longer suffices, theexhaust-steam also flows through the passage 1. From the steamchamber c'the exhaust-steam fiows through the pipe 21 in-to the valve g and intothe exhaust-pipe 22 in the direction of the arrows t. According to Fig.8, where the slide divides the two steam-chambers r s into two parts,the steam enters from the side .5' and s' and escapes at /1' and r andthe cylinder rotates in the direction of the arrow o. According to Fig.9 the sector 9 enters between the surfaces 17 of the jaws 13 and 13 andremains in this position also in Fig. 10, where the steam only exertspressure in the chamber s, since the passage 3 is closed against thechamber s by the sector 9. On further rotation of the screwblade lO anew chamber s is formed and the steam-pressure commences to act again init, so that there can never be a dead-point, and is always at least onechamber between the slide and the screw-blades filled with live steamand capable of acting. Should the direction of the motor have to bereversed, the valvebody 23 must be turned into the position o, so thatthe steam enters through the chamber c into the chambers fr and 7" andthe cylinder turns in the reverse direction. The exhaust-steam entersthe chamber c and passing through thc pipe 2l leaves at 22. There isthus always one steam-chamber serving for the steam-supply and the otherfor the exhaust, or vice versa.

What I claim, and desire to secure by Letters Patent, is-

1. A rotary motor comprising astationary cylinder provided on eitherside with passages, steam-chambers connected with said passages, afianged working member rotating in said cylinder, lrabe flange of saidrotating member dividing the working' chamber from the exhaust-chamber,a slide positively actuated by said flanged rotating member, said slidebeing' formed with a recess in which said flange is received,spring-pressed jaws mounted in said recess and bearing on the oppositesides of said flange, inlet-passages and exhaust-passages on either sideof said slide, an inlet and exhaust valve, and pipes communicating withsaid valve, the steam-chambers and a steam-boiler and exhaustrespectively.

2. In a rotary motor, the combination of a stationary cylinder, andsteam-chambers having opposite upper and lower inlet and exhaustpassages communicating with the cylinder, a flanged working memberrotating' in said cylinder, a slide actuated by the fiange of saidworking member, a governor, slide-valves for said upper passagescontrolled by said governor-valves closing the lower passages, a shafton which said working member is mounted,and means whereby said governoris operatively connected to said shaft.

3. In a rotary motor, the combination with a stationary cylinder, andopposite steam-'chambers having upper passages leading therefrom whichterminate in two passages communicating with the opposite ends of thecylinder, and lower passages having bifurcated inner ends communicatingwith the cylinder adjacent its opposite ends, a flanged working memberrotating in said cylinder, a slide e actuated thereby, a governor,slide-valves in the steam-chambers controlled by the governor foropening and closing the first-named passages, valves in thesteam-chambers for controlling the last-named passages, and an inlet andexhaust valve, and pipes communicatingI with said valve, the saidchambers and a source of steam-supply.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
